Interesting project! Keep up the good work

Iam in the same boat as you, what to do next :) My first pj was just lashed together and ran quite well as a heater. If you want some really awesome plans for a large 40 pound pj look up Metiz's m40. There is a comprehensive .pdf on one of the last couple pages of the thread, it has all templates re...

Hi there Francisco :) I recently subsribed to your channel and asked the question 'did you build these yourself?' Anyways brilliant engine, nice effort. Iam planning to build a valved dynajet in the future for an rc plane. I will learn to fly first though. Looking forward to more info and videos! Yo...

Hi mate have you got any updates too share?

Have you designed that car/kart yet? I like the idea of those aero dynamic down hill gravity powered cars with a pulsejet or two shoe horned on.

We want more video

Hi Joe, I can't stop coming back to this thread! I want to build one of these, would you be ok with me having a go at one? I have a load of 1mm mild sheet that needs using :) Regardless of actual figures, is it "powerful" for its size and shape, I know you havent pushed it hard yet but you must have...

nice one mate, congrats, itrs great too fire up your first pj

did it start up ok?? is there much diference between AFW and FWE? I wonder if the changes eric made were improvements!!

Thats running nicely, The ball valves are great for emergency shut-offs. Maybe if the handle was very long, 12 to 18 inches it would have better control. I find multiple needle valves in parallel give reasonable results. They can be the less expensive type, just need to make sure they have the fine...

What are the dimensions of the one labeled "mathew", that runs like mad! http://www.youtube.com/watch?v=32OY8Y9nkS0&feature=digest_sun Haha Thanks Joe, i was very happy when it fired up like that for the first time!! cc = 155mm long x 64mm id inlets are 2 x 8mm holes (drill snatched on 1 hole as ca...

Far from everything has been tried, I say give it a go. My speculation is the water has a high enough density it would interfere with the pumping effect of the tail. Instead of the pressure from the CC driving the tail pump, it will dump the pressure out the intake. The first cycle would be good, b...

I have this random question that i have been searching for an answer. if i had a thermo-jam or similar and hasd it mounted horizontal with the tail slightly pointing down into some water, just under the surface of the water, what will happen? will it still run? maybe there isnt an answer until i try...

Pyrojoe i found this needle valve available in the uk for £30 (about $50) is this more suitable than my ball valves? http://i.ebayimg.com/22/!B0lYMq!!2k~$(KGrHqEOKi0E)RScVoE(BM,9iBqQn!~~_35.JPG http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110575221716&fromMakeTrack=true&ssPageName=VIP:watchl...

Last night i made another larry spec stinger using 2 x M5 countersunk screws welded head to head with a .2mm gap instead of the .5mm gap (.5mm gap un tested on an engine). i setup the fuel line and stinger in an adjustable fashion and commenced start up attempts once more. so as i intended, i only s...
